摘要：

For a variety with weak existentially definable factor congruences, we characterize when the properties "(e) over right arrow is a central element" and "(e) over right arrow and (f) over right arrow are complementary central elements" are definable by (for all Lambda p = q)-formulas and by (Lambda p = q)-formulas.
